Main goals of this project were creation of finite-element model of Vacuum Investment casting produced from nickel-based superalloy, simulation of filling and solidification processes, and determination of shrinkage porosity in casting.

As a result of simulation we got temperature distribution in casting and mold during the process, revealed zones of high flow velocity, hot spots in casting and places with a macro and micro porosity.

Detected shrinkage porosity in turbine vane carrier may decrease of working characteristics and even may cause of part’s destruction.
